Installation notes and dimensions
The steam distribution pipes are designed for either horizontalinstallation(ontheductwall)or,with
accessories, for verticalinstallation(intheductoor).Theoutlet orices should always point up-
wards and at right angles to the airow.
If possible, the steam distribution pipes should be installed on the pressure side of the duct (max.
duct pressure 1500 Pa).Ifthesteamdistributionpipesareinstalledonthesuctionsideoftheduct,
the maximum vacuum must not exceed 1000 Pa.
